This study was conducted to determine the effects of housing systems (free-range and conventional cage) during the egg-laying phase on the growth, egg production, overall egg weight, and egg quality traits of a new Turkish laying hen hybrid, Akbay. A total of 600 (300 hens per housing system) Akbay laying hen hybrids were used in this study. At the end of the rearing cycle (17 weeks) the average live weight and cumulative feed intake for both groups were 1150.8g and 5067.52g, respectively. The live weight and cumulative feed intake at the onset of laying for both groups were 1198.42g and 5537.77g, respectively. Egg production, average daily feed intake, and average daily feed conversion ratio were significantly higher (p≤0.05) in free-range hens than in hens housed in cages. The live weight at peak production was significantly higher (p≤0.05) in hens housed in cages than in free-range hens. Significant differences (p≤0.05) in terms of internal and external egg quality traits were observed between the housing systems in this study. Generally, the free-range hens had better performance than the hens in cages. It was therefore concluded that the growth performance, egg production, overall egg weight, and egg quality traits of the new Turkish laying hen hybrid Akbay are better in the free-range production system than in convention cages; and that these hens can be housed in the free-range system without any negative effect on performance and egg quality traits.
